Over the decades I've probably owned a hundred holsters, most of which did a poor job or turned out to be of poor quality. I currently own two Milt Sparks VM II's, a Kramer vertical scabbard and a Bulman SDS ............ and I've started making my own.
I try to have one for each of my pistols.
Now that I have my CCW, I try to have a pocket and IWB for the mousegun(s), and an IWB and OWB for the sub-compacts. Have three on order and looking for that just one more . . . .
